This paper focuses on the assessment of college Specialty Construction Project quality. On the basis of conducting researches and analysises of Specialty Construction Practice, the anther selected projects indicators of construction content with high frequency as evaluation index constituent connotation, referring to professional evaluation index system of provincial brand, and defended the issue that there will be no characteristic projects of specialty evaluate; formed the basic architecture of local colleges specialty evaluation index system, clearing grading assessment model, making debate analysis on its value orientation; and confirmed that the Ministry of Education is the main project, the university is the main building, and the provincial education administrative departments or the third party certification is the assessment mainbody, in this way to constitute the innovation management mode of Specialty Construction. 展开更多

Perovskite solar cells(PSCs)commonly exhibit significant performance degradation due to ion migration through the top charge transport layer and ultimately metal electrode corrosion.Here,we demonstrate an interfacial management strategy using a boron chloride subphthalocyanine(Cl_(6)SubPc)/fullerene electron-transport layer,which not only passivates the interfacial defects in the perovskite,but also suppresses halide diffusion as evidenced by multiple techniques,including visual element mapping by electron energy loss spectroscopy.As a result,we obtain inverted PSCs with an efficiency of 22.0%(21.3%certified),shelf life of 7000 h,T_(80) of 816 h under damp heat stress(compared to less than 20 h without Cl_(6)SubPc),and initial performance retention of 98%after 2000 h at 80℃in inert environment,90%after 2034 h of illumination and maximum power point tracking in ambient for encapsulated devices and 95%after 1272 h outdoor testing ISOS-O-1.Our strategy and results pave a new way to move PSCs forward to their potential commercialization solidly. 展开更多
